Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00126 - 0.00477), b=3.19 (3.02 - 3.36), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref.
120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
